sna/dri2: Avoid trying to flip between bo with different pitches
It could happen that we create front/back buffers with different
pitches. The kernel refuses to flip between such buffers, and so we will
hit some fallback paths that try to fix up the failed flips. Circumvent
such by avoiding the flip.
